GIUSEPPE DI DID, OF NEW YORK, N. Y.

To all whom it maly concern Be it known that I, Ginsnrrn DI Dio, asubject of the King of Italy, and resident of the city, county, andState of New York, have invented certain new and useful Improvements inShoe Heels, of which the following is a specification.

The present invention relates to shoe heels, and more particularly tothe type which may be detached from the shoe for interchanging and forfurther'use.

An object of the present invention is to provide a shoe heel of themetallic type which is relatively light in weight and which provides astrong structure, and which is arran ed to carry a rubber, leather orother suitable bottom lift which may be detached by the usual nails, anda heel structure which may be secured to the heel part of a shoe by ascrew or the like which is operated independently of the lift screwingdevices.

Another object of the invention is to pro vide a hollow heel structurewith a screw receiving post so arranged within the heel structure as toequally distribute the stress incident to the tightening of theattaching screw evenly at the front and rear portions of the upper endof the heel, or where the heel comes in contact with the out sole orother adjacent heel part of the shoe so as to bind the heel with anequal firmness entirely about its upper edge.

A further object of the invention is to provide a fastening device for aheel which permits of the loosely fastening of the heel to place, thesubsequent adjustment of the heel into the final required position, andthe tightening of the heel so as to firmly hold it in the finallyadjusted position, all of such adjustments and fastenings beingindependent of thelift retaining devices and in no way disturbing therelation of the same to the heel of the shoe.

The invention has for a still further obj ect to provide a hollowmetallic heel with a cavity in its lower end into which may be fitted aplurality of layers of leather or other nail receiving lifts which areof suitable depth or thickness, and into which may be driven nails orthe like for holding in place a rubber, leather or other suitable bottomlift; to provide a heel securing device which operates at substantiallyright angles to the plane of the upper end of the heel to bind the sameevenly against the underside of SHOE HEEL.

Application filed January 9, 1922. Serial No. 527,899.

the shoe; to provide a fastening device for the heel which is locatedsubstantially cen trally of the upper end of the heel and which permitsthe heel to be turned axially on the fastening means to obtain desiredadjust ments of the heel; and to provide a heel fastening means whichmay be anchored or secured in final position to prevent displace ment ofthe heel.

With the foregoing and other objects in view, the invention will be morefully described hereinafter, and will be more particularly pointed outin the claim appended hereto.

In the drawings, wherein like symbols refer to like or correspondingparts through out the several views,

Fig. 1 is a fragmentary sectional view taken longitudinally andvertically through a heel constructed according to the present inventionand through the adjacent part of a shoe.

Fig. 2 is a top plan view of the heel detached.

Fig. 3 is a bottom plan view of the heel, the lower lifts being removed.

Fig. 4: is a bottom plan view, partly broken away, of the heel with thelower lift removed and the nails shown in section.

Fig. 5 is a bottom plan view of the heel, showing a slight modificationin the fasten-. ing means therefor.

Referring to the drawing 10 designates the body portion of a shoeprovided with the usual out sole 11 which extends into and forms aportion of the heel part of the shoe.

The body portion 12 of the heel may be formed of aluminum or othersuitable light metal, and which is given the general configuration of aheel with the flaring upper end shaped to conform to the lower side ofthe heel part of the shoe and with its lower end tapering and extendingdownwardly to the desired extent. The body portion 12 of the heel ishollow and is provided with a relatively horizontal partition 18 locatedintermediate the top and bottom portions of the heel body, and whichprovides a relatively deep cavity 14 in the lower end of the heel. Thecavity 14 is adapted to receive a plurality of relatively thick lifts 15of leather or the like which are of suitable material for receivingnails and such fastening devices of suitable length for attaching to thelower end of the heel and final lift 16 of rubber, leather or othersuitable wearing material. The lifts l5 and the cavity 14: are ofsuitable depth so that long nails 17 may be used, and so that no otherfastening devices for the lower lift 16 wil l. e found necessary.

The heel is secured to the body portion of the shoe by a,v clampingscrew '18 which is positioned downwardly through the out sole 11 fromthe interior of the shoe, and which enters a post l9 arranged within thehollow body portion 12 of the heel, and into which the screw 18 isadapted to be turned for tightening the screw in the post and against.the out sole '11. The post 19 is not disposed in axial alineinent withthe heel as is usual, but is located rearwardly of the verticai axis ofthe heel and. is inclined forwardly so as to dispose the axis of thepost 19 substantially at right angles to the plane of the upper edge ofthe heel 12. This tilting or inclination of the post 19 causes a directpull or tension upon the post when the screw 18 is turned down into thepost, which pull or tension is distributed equally in all directions tothe post 19 so thatthe front, rear and lateral edges of the upper partof the heel are bound with equal force or stress against the adjacentlower surface portions of the out sole 11 and the adjacent parts of theshoe.

The post 19 is thus located in a. substantially central position withrespect to the upper end of the heel'and when the screw 18 is turnedinto the" p'ost19 to extend sufiiciently for loosely holding the heel inplace, the heel may be turned into various positions until the desiredadjustment is reached, when the screw 18 may then be tightened to bindthe heel in place. If desired, additional fastening devices may be usedfor retaining the heel body 12 from turning on the shoe, and as shown inthe present instance these additional fastening devices comprise screws20 which are countersunk in the outer surfaces in the heel body 12 nearthe upper forward edge thereof, and which engage in the out sole 11. Asshown in Figs. 2 and -3, a pair of these screws 20 may be employed, oras shown in Fig. 5, a single screw it) may be used, andin the lattercase asingle screw is located intermediate the lateral edges of theheel.

The lifts 15 are held in the cavity let by an axially positioned screw21 which extends upwardly cit rongli the lifts l5 and is threaded in thepartition 13. The screw :21 tern'iinates in the partition 13 so that thescrew is relatively short and may be of small diameter to thus reducethe weight and size of the complete heel.

The heel is provided with a surface co vering 22 of leather, cloth orother suitable material. to match the particular shoe body to which theheel is to be applied. is shown, the lower portion of the (rover may heturned. inwardly about the ma ginal edge portion ,of the carity l3 andcia red therein by the lifts l5 so that the covering and the lifts maybe bound together in the cavity by the axial screw 21.

There has been illustrated preferred and satisfactory forms of thisinvention, but it is obvious that this may be made therein within thespirit and scope thereof, as defined in the appended claim.

It will be noted that the part 15 can be changed when worn out. Themetal heel i self can be used over again when the shoes are worn, andput on a. new pair or other pair of shoes. Great economy can thereby beeffected.

What is claimed is:

A shoe heel comprising a hollow body having an open upper end presentingthercai a relatively deep recess with its niargii'ial edge incliningfrom the hack to the breast of the heel body, said heel body having a.post inclining forwardly from the rear wall. of the body atsubstantially right angles to the plane of the upper edge of the bodyand at the center thereof, and a screw threaded axially in the post andadapted to engage through the sole of the shoe for binding the sameevenly about. the edge of the heel body, said post teri'ninating belowthe plane of the upper edge of the heel body to permit the sole toextend downwardly into the recess in the top of the heel body and settleagainst the upper edge thereof at all sides, the breast portion of theheel body at itsupper end having an opening therein adapted to receivean anchoring device subsequent to the clamping of the screw.

Intestimony that I claim the foregoing as my invention I have signed myname hereunder.

GIUSEPPE DI D10.
